Title: Inventor François Rieutord: Innovations in Substrate Bonding

Introduction

François Rieutord is a distinguished inventor located in Saint Egrève, France, with an impressive portfolio of 8 patents. His innovative work primarily focuses on advanced methods of substrate bonding and layering techniques that have wide applications in various technological fields.

Latest Patents

Among François Rieutord's latest patents is a groundbreaking method for transferring a useful layer. This method involves creating an embrittlement plane by implanting light elements into a first substrate. A useful layer is then formed between this plane and one surface of the substrate. The technique includes applying a support to the surface, creating an assembly that is subsequently fractured through a heat treatment, initiating a fracture wave along the embrittlement plane. Notably, the speed of the fracture wave is controlled to ensure that vibrations remain localized to the peripheral area of the useful layer.

Another recent patent by Rieutord centers on the direct bonding of substrates, which includes thinning the edges of at least one substrate. This method involves thinning the edges of the first substrate and placing it in contact with the second substrate to facilitate direct bonding. A bonding wave propagates between the substrates, creating a secure attachment where the thinned portions of the first substrate adhere to the second substrate effectively.
